Verfahren für Aktualisierung des microprogramme eines Sicherheitsmoduls

摘要

The method involves diffusing a stream comprising corrective messages (EP) adapted to update a micro-program e.g. firmware, of a safety module e.g. smart card, and adding switching message in a stream of administration messages e.g. entitlement management messages (EMMs). The module is directed towards the corrective message stream if a current version of the micro-program is lower than a corrective version. The micro-program is updated with the corrective message stream. The module is directed towards the stream of administration messages when the updated micro-program is terminated.
